Design and development of Z source cascaded seven level inverter for solar photovoltaic system

This paper presents Z-source multilevel inverter (ZS-MLI) for photovoltaic (PV) operation. MLI maintain the gain of higher power efficiency and can run with higher voltage level. As the number of levels rises, the chose sinusoidal waveform can be attained for lesser total harmonic distortion (THD). Z-source network followed by the cascaded H-bridge multilevel inverter is used to upgrade the output voltage to a chose value. This work proposes an enhanced Z source network multilevel inverter. The simulation of single phase, seven level Z-source cascaded MLI is executed using MATLAB/SIMULINK.
